Population Genetics_
AP Biology - Review of Population Genetics and Evolution
| Question | Answer |
|---|---|
| Evolutionary change below the species level; change in the allele frequencies in a population over generations. | microevolution |
| A graded change in a character along a geographic axis. | cline |
| A group of individuals of the same species that live in the same area and interbreed, producing fertile offspring. | population |
| The principle that frequencies of alleles and genotypes in a population remain constant from generation to generation, provided that only Mendelian segregation and recombination of alleles are at work. | Hardy-Weinberg principle |
| The condition describing a nonevolving population (one that is in genetic equilibrium). | Hardy-Weinberg equilibrium |
| A process in which chance events cause unpredictable fluctuations in allele frequencies from one generation to the next. Effects of genetic drift are most pronounced in small populations. | genetic drift |
| Genetic drift that occurs when a few individuals become isolated from a larger population and form a new population whose gene pool composition is not reflective of that of the original population. | founder effect |
| Genetic drift that occurs when the size of a population is reduced, as by a natural disaster or human actions. Typically, the surviving population is no longer genetically representative of the original population. | bottleneck effect |
| The transfer of alleles from one population to another, resulting from the movement of fertile individuals or their gametes. | gene flow |
